To all whom it may concern:

that I, King of of N 0. l6 Friedrichstrasse,

Germany, and useful Improvements in Skittles, of which the following isa specification.

The present invention has reference to skittles which are provided witha springinfluenced ball, housed and protruding partly face for thepurpose of ing socket in the stand the skittles, so as to insure andguarantee the proper setting up and corelative position of Be it knownsubject of the the Empire of the latter.

With th and adaptation hereinafter explained, panying drawin'gs out inthe appended claim.

In the annexed drawings Figure 1 shows a central vertical part of askittle Z7 h threaded at the by the reference letter provided withfemale screw threads f at its end is secured on -tu ular boss 6 issha edshell 9 which snugly fits the internal surface of the boss e and abutsagainst the step portion h le top portion f when the marginal cup edge 6registers with thebottom edge 7c of the boss A coiled spring Z isinserted into the cylinder a, said spring eing adapted to press againsta piston m which guided in the cylinder 0 and the boss e and shell 9. ThI piston m acts upon a ball '12 placedinto the cup-shell 9, when thelatter is inserted in the boss e and when the boss cylinder 0 as shownin pressure of the the ball n is forced Fig. 2 is an inverted plan viewof the same.

My invention comprises the following com ponent parts, which sembled inthe following manner.
